President Obama did not issue a proclamation. He issued a statement wishing Muslims in the U.S., and all around the world, best wishes from himself and the First Lady. The difference between a Presidential Statement and a Presidential Proclamation is the difference between a skateboard and a racecar. Furthermore, as Julie Millican of Media Matters writes:

I do know this: Former President George W. Bush issued a statement honoring Ramadan in 2008, and Fox didn't have a problem with it.

* It is really unfair to call this a smear, since there is nothing wrong with being a Muslim and it hasn’t been made illegal…yet. However, since Fox News is heavily invested in turning Islam into the enemy of all that is Holy and Good in ‘Merka, it is a smear in their eyes.
